Application February 5, 1948, Serial No. 6,372

truck without the necessity of removing the car body, therebyappreciably decreasing the time and cost of repair and lubrication ofjournal boxes to a minimum.

An important object of the invention is to provide a journal box whichwill be held in place by the weight of the rolling stock supportedthereby,

eliminating the use of bolts or nuts, commonly employed in securing andadjusting journal boxes with respect to the axles.

With'the foregoing and other objects in View which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts, hereinafter more fully describedand pointed out in the claim, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

Referring to the drawings:

Figure 1 is a side elevational view of one end of a truck side frame ofrailway rolling stock, illustrating a journal box, constructed inaccordance with the invention, as mounted thereon.

Fig. 2 is a plan view thereof, a portion of the truck frame being shownin section.

Fig. 3 is a vertical sectional view through the journal box illustratinga car axle as fitted therein taken on line 33 of Fig. 4.

Fig. 4 is a vertical sectional View taken on line 4-4 of Fig. 3.

Fig. 5 is a plan view of the journal box.

Fig. 6 is a side elevational view thereof.

Fig. '7 is an end elevational View of the journal box.

Fig. 8 is an end elevational view illustrating the journal box openingformed at one end of the side frame of a truck frame.

Fig. 9 is a sectional view taken on line 9-9 of Fig. 8.

Fig. 10 is. a vertical sectional view on line 'l0l0 of Fig. 9 with themembers 5 and 9 assembled.

Referring to the drawings in detail, the reference character 5 indicatesone end of a truck side frame, forming a part of railway rolling stock.

As clearly shown by Fig. 8 of the drawings, the truck side frame isformed with journal box openings which are formed with upper recesses 6and lateral vertical grooves 1, the grooves l and recesses 6 beingformed in the wall of the journal box opening.

The grooves I have one of their respective walls cut away as at 8providing entrances to the vertical grooves I, the cut-away portions 8extending inwardly from the outer edge of the journal box opening.

The journal box forming the subject matter of the present invention isof the roller bearing type and is adapted for use with practically anytype of roller bearing now in production.

As shown, the journal box includes a substantially circular housing 9 inwhich the roller races II], are mounted, the roller races supporting therollers II.

The housing 9 is somewhat smaller in diameter than the diameter of theopening in the truck frame, and has extending upwardly from the uppersurface thereof, an enlargement [2 adapted to fit closely within therecess 6, the formation of the enlargement I2 being such that it willmove readily into the recess 3 and be held therein by the weight of thecar body, supported thereon.

Extending from opposite sides of the housing 9, are wide lugs l3 whichhave rounded outer edges designed to fit within the grooves 1. Onpositioning the journal box, it is to be understood that the truck framewill be elevated by means of a suitable jack, whereupon the lugs l3 willfall opposite to the cut-away portions 8. With the weight of the carbody removed, the journal box may now be readily slid from the openingwithin the truck side frame. Removal of the journal box may be desirablein order to repair or replace worn parts in the bearings of the journal,or it may be necessary to repack the bearings. The journal may afterrepairs or repacking, be readily positioned on the axle of the rollingstock, in such a way that when the lifting jack is removed, the Weightof the car body will cause the truck frame to move downwardly, the lugspassing into the vertical grooves I, while the upper recess 6accommodates the enlargement l2 preventing twisting of the journal box.

Having thus described the invention, what is claimed is:

In combination, a truck frame having a circular journal box opening, thewall of the journal box 0 opening having a recess formed thereinadjacent REFERENCES CITED to ofgthe Journal 9 P the W The followingreferences are of record in the of sand Jotililrnalt box opeii nghazing1 verftlcal fil of this patent: grooves W1 cu -away por lOIlS exen mg rom the lower ends of the grooves to the outer edge of 5 UNITEDSTATES PATENTS the opening, a circular journal box having lugs NumberName Date extending from the sides thereof movable in the 2 M Ord July16, 1918 grooves and the cut-away portions, and an en- 1,343,618 0 lrJune 15, 1920 largement formed on the top of the journal box, 1,636,757e bu July 26, 1927 fitted into the recess and retaining the journal 102,047,243 Baahman ly 19, 1936 box in position within the journal boxopening.
